INTERLOCKING RIG MATS

摘要

A rig mat comprising a downwardly sloping first end comprising a female coupling and extending across a first lateral end of the rig mat and an upwardly sloping second end comprising a male coupling and extending across a second lateral end of the rig mat. Each of the downwardly sloping first end and upwardly sloping second end is in the form of a triangle comprising three angles that total one hundred eighty degrees. The downwardly sloping first end comprises a sloped flat surface and a bottom surface that is level with a bottom surface of the rig mat. The upwardly sloping second end comprises a sloped flat surface and a top surface that is level with a top surface of the rig mat.

1. A system of interlocking rig mats, each rig mat comprising:
(a) a downwardly sloping first lateral end comprising a female coupling and extending across a first lateral end of the rig mat; (b) an upwardly sloping second lateral end comprising a male coupling and extending across a second lateral end of the rig mat; wherein each of the downwardly sloping first lateral end and upwardly sloping second lateral end is in the form of a triangle comprising three angles that total one hundred eighty degrees; wherein the downwardly sloping first lateral end comprises a sloped flat surface and a bottom surface that is level with a bottom surface of the rig mat; wherein the upwardly sloping second lateral end comprises a sloped flat surface and a top surface that is level with a top surface of the rig mat; wherein adjacent rig mats are configured to lock together laterally, and the weight of one rig mat is distributed evenly along the entire surface of the downwardly sloping first lateral end of an adjacent rig mat when the rig mats are locked together (p. 14; FIG. 18); wherein the adjacent rig mats are configured to allow rotational movement of one rig mat relative to an adjacent rig mat when the rig mats are locked together (p. 13); wherein the adjacent rig mats create a continuous planar surface when locked together (p. 14; FIG. 1A); and wherein the downwardly sloping first lateral end is configured to form a ramp to allow vehicular access to the continuous planar surface (top p. 9; FIG. 1B).
